Man says he's eaten 23,000 Big Macs since 1972

A 54-year-old man says his obsessive-compulsive disorder drove him to eat 23,000 Big Macs in 36 years. Fifty-four-year-old Don Gorske says he hit the milestone last month, continuing a pleasurable obsession that began May 17, 1972 when he got his first car.

Gorske has kept every burger receipt in a box. He says he was always fascinated with numbers, and watching McDonald's track its number of customers motivated him to track his own consumption.

The only day he skipped a Big Mac was the day his mother died, to respect her request.

The correctional-institution employee says he doesn't care when people call his Big Mac obsession crazy. He says he's in love with the burgers, which are the highlights of his days.
